- CONVERTIBLE CHAIR AND VELOCIPED E.

SPECIFICATION forming part of Letters Patent No. 333,414. dated December29, 1885.

Application filed September 8, 1885. Serial No. 176,546.

To all whom it may concern.-

Be it known that I, WILLIAM HOLDEN, a citizen of the United States,residing at Baldwinsville, in the county of Worcester and State ofMassachusetts, have invented new and use ful Improvements in aConvertible Chair and Velocipede, of which the following is a speci- Myinvention relates to a chair that is convertable as to height andadapted to be used as a velocipede when lowered.

The invention consists in the combination, with a childs convertiblenursery-chair having traction and guiding wheels and propelling 1gearing,of a crankshaft for actuating the propelling mechanism; and italso consistsin the combination,with a chair-frame and convertible orshifting seat,of aseries of links or levers pivoted to said seat and tothe sides of the chair-frame for the purpose of changing the position ofthe seat as required.

The invention also consists in certain peculiarities in the constructionand combination of parts,as hereinafter set forth,and particularlydefined in the claims.

In the annexed drawings,illustra ting the invention,Figure l is a sideelevation of the chair in its raised position. Fig. 2 is a centralsection of the chair lowered with seat shifted ,and Fig. 3 is a detailview.

The chair-frame A consists of bars a a,that form the legs of the chairwhen placed upright, said bars a a being connected on the sides of theframe by cross-bars b c d e, in front by bars f g h, and at the rear bycross-bars t k. The lower cross-bars,b b,are connected by a bar orround, Z, and the bars at e on each side are connected by verticalstruts m.

The seat-frame B is made in any-suitable or convenient form with backand arms,as usual. To each side of this seat-frame, at its rear end, ispivoted one end of a link, j, the opposite end of which is pivoted tothe inner side of the upper crossbar, e, at or near the center. The 45forward end of the seat-frame B is provided with lugs n, to which arepivoted the upper ends of links 0 0, the lower ends of which are pivotedto the inner sides of the cross-bars d at or near the center.

When the chair is in an upright position,as shown in Fig. 1, with theseat-frame B resting on the upper front and rear cross-bars,h and k,

(No model.)

the linksjj will rest in a horizontal position substantially parallelwith and between the upper cross-bars, e, and the sides of theseat-frame, While the links 0 0 will occupy a diagonal position inclineddownward from frontto rear. In this position the seat-frame is securedby the engagement with a catch, p, attached to one of the uppercross-bars, e, of a spring-bolt; q, or other fastening attached to oneside of said seat-frame. By disengaging the catch 19 and bolt q, andthen raising the rear end of the seat-frame and tilting itforward,thechair-seat can be made to rest upon the front cross-bars, gh, in which position it may be secured by the engagement of the springbolt q with a catch, 1", attached to one of the bars or legs a. With theseat-frame B in this position the chairframe A will be turned backwardand lowered until its legs or bars a a are in a horizontalposition, asshown in Fig; 2. The linksj and 0 have been thrown forward in the act ofconverting the chair from a high chair to a low chair; but while thelinks 0 rest diagonally in both positions of the seat-frame, the links jare now vertical and at right angles to the seatframe,though stillparallel with the cross-bars e,which are also vertical in this positionof the chair.

To the front legs of the chair, on their inner sides and beneath theends of the cross-barsg, are pivoted angle-irons s s, that support afootrest or step, 0, the pivoted angle-irons being actuated by the links 00,by means of connect- 85 ing rods or bars it, so as to throw thefootrest forward when the chair is elevated with seat resting on thecross-bars h h, as shown in Fig. 1, and to retract said foot-rest withinthe chair-frame and beneath the seat, as shown in go Fig. 2, when thechair is lowered with seat thrown forward. The links j 0, angle-irons s,and connecting-barst thus serve to produce a simultaneous movement ofthe seat-frame and loot-rest without interference of one with the other.The lowered chair may be allowed to rest on the sides of the rear bars,a,.or the chair-frame can be provided with wheels or rollers by which,when lowered,it is made ca pable of use asa carriage or perambulator.

In order to arrange the lowered chair for use as a velocipede orperambulator, an axle, D, is journaled in the struts m or at any otherconvenient pointin the chair-frame. This axle IOO ' barsf and Z, theupper end of the rod or shaft m being provided with a pivoted handle, N,by which the occupant of the chair or velocipede can control itsmovements while propelling it with feet upon the cranked pedal-shaft.

Heretofore a chair has been made convertible at pleasure into a highchair on legs or a low chair on wheels, and the leg-frame has beenconstructed so that it serves both as a support for the chair and forthe wheels and their bearings. I do not therefore claim these features,broadly.

What I claim as my invention is 1. In a convertible chair capable of adjustment as to height. the combination, with a chair frame, a shiftingseat-frame, and a movable foot-rest, of pivoted angle-irons forconnecting said foot-rest to the front of the chair-frame, links forconnecting the forward and rear ends of the seat-frame to the innersides of the chair-frame, and bars or rods for connecting the forwardlinks of the seat-frame to the angle-irons that support the foot-rest,whereby the seat-frame and foot-rest may be shifted or adj ustedtogether, substantially as described.

2. In a convertible chair, the combination,

with a chair-frame having cross-bars d e and a shifting seat-frameprovided at its forward 'end with lugs n, of the links j, pivoted to thewith a chair-frame and a shifting seat-frame,

said parts being capable of a relative adj ustment to vary the height ofthe chair, of the links j,pivoted to the inner sides of the chairframeand to the rear end of the seat-frame,and the diagonal links 0, having apivotal connection with the inner sides of the chair-frame and with theforward end of the seat-frame, the said links-j being vertical and atright angles to the seat-frame when the chair is lowered, and occupyinga horizontal position between the chair-frame and seat-frame when thechair is elevated, substantially as described.

4. In a convertible childs chair and velocipede, the combination,- witha leg-frame having traction-wheels journaled near one end, a guide-wheelnear the other end, and an intermediate crankshaft connected with thedriving or traction wheels,ofa shifting seat adapted to rest upon theend of theleg-frame,when set upright or upon the side thereof,whenturned' down to rest upon the wheels, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM HOLDEN.
